Hi all, I’m 1 year into cycling and have been using sufferfest for the past 3 months. I’ve seen some great gains in my FTP since using sufferfest (~15% FTP increase, ~18% MAP increase), but today I did a HM test and my LTHR was super high! If it’s accurate then I will be super chuffed, but I’m wondering what the chances of error is in HM and 4DP for LTHR? Below info for full context:
- 4DP on 15 May 2019 - LTHR of 168 detected (~88.4% HRmax). Felt fresh.
- 4DP on 29 June 2019 - LTHR of 164 detected (~86.3% HRmax). Was carrying some fatigue.
- HM on 12 August 2019 - LTHR of 175 detected (~92.1% HRmax). Testing after 3 full days complete rest/inactivity.
- the past 6 weeks since last test I have been training very hard, a lot of time spent at racing intensity sitting in high heart rate zones. Every week I have reached or been within 2 beats of HRmax.
Has anyone had similar LTHR improvements? Is my improvement legitimate or potentially an error?
